Control via PROFIBUS DP
The outputs of the module can be set direct via PROFIBUS DP (by a PLC, for example) via
the PROFIBUS DP bits that are transferred via data set 69 to byte position 13. Together with
the digital input module, it is possible to integrate switchgear that does not have direct
communications capability into a communication system.
Status detection
The status can be read in via the input module. With this, for example, a motorized operating
mechanism could be switched on or off via the digital configurable output module. However,
many other diverse applications are conceivable.
Threshold delay
In contrast to the digital output module with rotary coding switch, it is not possible to add a
time delay to the event. If, for example, a threshold value is to be output with a delay via the
digital configurable output module, this can only be achieved by delaying the threshold value.

LED indicator
As on the digital output module with rotary coding switch, this module also indicates the
status of the outputs via the labeled LEDs. The table below contains a list of all events on the
CubicleBUS that can be output via the digital configurable output module.
These events are available to the digital configurable output module
